On the analysis of spectral deferred corrections for differential-algebraic equations of index one
Matthias Bolten, Lisa Wimmer
In this paper, we present a new spectral deferred corrections (SDC) method to solve semi-explicit differential-algebraic equations (DAEs) with the ability to be parallelized. The n…

Analysis on aggregation and block smoothers in multigrid methods for block Toeplitz linear systems
Matthias Bolten, Marco Donatelli, Paola Ferrari +1
We present novel improvements in the context of symbol-based multigrid procedures for solving large block structured linear systems. We study the application of an aggregation-base…
